In the interest of maintaining a similar layout per report type, I have copied one report to another file name, then modified the new file query. When doing this, the records do not show up underneath the query in the Data window e.g. Data->Data Sets->JDBC->Query1 does not display the fields underneath Query1.

When creating the report 'from scratch', the records show up.

Is there something that needs to be modified in the new file when copying from an old?
